Long time K&N filter user on 6 vehicles so far. You can feel the difference immediately after the install. Nothing tremendous but noticeable in acceleration startups. Quality have always been great. Pre-oiled filter lasts 50k miles which is a plus, I usually tend to clean and re-oil more often than needed.
